Corning Culture Flask 150 cm2 U-Shaped Canted Neck Vent Cap Case of 50 Flasks

Corning 150 cm² U-Shaped Cell Culture Flask with Vent Cap (430825)

The Corning 430825 is a premium 150 cm² T-flask engineered for the consistent growth and maintenance of anchorage-dependent cell lines. Manufactured from high-clarity, medical-grade virgin polystyrene, this flask features a specialized U-shaped profile that enhances structural stability and improves pipette access to all corners of the growth surface. The surface is treated with the industry-standard Corning CellBIND or Tissue Culture (TC) treatment (please verify specific lot) to ensure optimal cell attachment and uniform spreading. Each flask is equipped with a 0.2 µm hydrophobic vent cap, which facilitates continuous, sterile gas exchange while providing a secure barrier against contamination. Delivered gamma-sterilized and certified non-pyrogenic, the 430825 is the premier choice for researchers performing protein expression, vaccine research, and large-scale cell expansion.

Technical Performance and Design

• Ergonomic U-Shaped Geometry: The rounded "U" shoulders provide a stable base and eliminate the sharp corners found in traditional rectangular flasks, making it easier to recover cells with scrapers or serological pipettes.

• Canted Neck Design: The angled neck allows for effortless pouring and improved pipette access, reducing the risk of "sloshing" and accidental contamination of the neck area.

• High-Efficiency Vent Cap: The integrated 0.2 µm pore size membrane allows for consistent oxygen and CO2 exchange, maintaining proper pH levels without the need to loosen the cap during incubation.

• Optically Clear Growth Surface: Provides a distortion-free window for microscopic observation, allowing for precise monitoring of cell confluence, morphology, and health.

Key Benefits & Applications

• Adherent Cell Culture: Specifically optimized for the expansion of mammalian cell lines such as CHO, HEK293, and primary fibroblasts.

• Scalable Cell Expansion: The 150 cm² area provides a significant increase in surface area over standard T-75 flasks, reducing the number of vessels required for large batches.

• Aseptic Gas Exchange: The vent cap is essential for incubators with high humidity or CO2 levels, ensuring a closed system that protects against airborne microbes.

• Low-Volume Media Efficiency: The flat, uniform growth surface ensures that even small volumes of media provide full coverage, maximizing the use of expensive growth factors and sera.
